IMPROVEMENT IN CLOCK-CASES.

Specin'cation forming part of Letters Patent No. 167,963, dated September 21, 1875 application filed July 29, 1874.

To all whom t 'may concern Be it known that I, WILLIAM N. WEEDEN, ot Waterbury, in the county of New Haven and State ot' Connecticut, have invented a new Improvement in Clock-Sash; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ot' this specification, and represent, in-

Figure l, a side View; Fig. 2, a transverse section, and in Figs. 3, 4, and 5, transverse sections.

This invention relates to an improvement in the manufacture of the sash or frames which incloses the glass or dial cover ot clockcases; and it consists in a sash formed ot' a single piece of metal, the shoulder or rabbet for the glass made by doubling the metal inward, as more fully hereinafter described.

A disk ot sheet metal is first struck or spun, then the edge turned up at right angles from the disk, and curved outward, as seen in Fig. 3. This done, the center A is cut out. The blank or ring is then subjected toa second operation ot spinning or striking' to forni a partial shoulder, as at a, Figa/1. The blank is then subjected to another similar process, by Which the metal on the shoulder a is doubled, so as to form an internal flange, d, leaving Athe rabbet B upon the inside to receive the glass, the outer portion C brought into a desirable mold shape. The extreme edge is then turned under to form a bead,f,v as seen in Fig. 2. Thus is produced the sash complete in one and the same piece.

I claim- The hereindescribed sash for clock-fronts,

formed from a single piece ot metal, the shoulder d produced by doubling the metal inward, substantially as set forth.
